Abstract (en)

[origin: WO2005021300A1] The present invention relates to a controlling method of an air conditioning system for vehicles. The method of the present invention includes the steps of: setting up a target indoor temperature of a vehicle determined by a user; inputting the indoor and outdoor temperature of the vehicle and solar radiation with referencing to a sensor mounted on a certain position of the vehicle; calculating a target discharge temperature (T1) of a vent; inputting the maximum evaporator temperature (T2); setting up a target evaporator temperature by comparing the T1 with the T2; calculating the opening degree of a temperature control door; measuring actual evaporator temperature while controlling the discharge capacity of a compressor; calculating an output value of each operation part by using the actual evaporator temperature and the opening degree of the temperature control door determined by the target discharge temperature; and outputting the calculated output value of the operation part.
